Can I epoxy the side imaging transducer in the hull of my fiberglass boat and allow the sonar to shoot through the hull?

Side
Imaging transducers have beams that shoot out to the side of the transducer therefore
they cannot be epoxied into the hull and work properly. Down Imaging
transducers can be. However, it is extremely critical that you use a
slow cure (24 hours or longer) two part epoxy. Quick cure epoxy can
cause air bubbles to form in the epoxy that will inhibit the transducer
signal. 9 out of 10 times that we have complaints about a transducer
not shooting through the hull properly tie directly to the epoxy and actual
installation of the transducer.
